:To -all whom it may concern:

. Be .it known thatiiI, CLINTON IE. Fnos'r,

a citizen of the United :States, and a resident of EastCleveland, county 'of Cuyahoga, and

State ofOhio, have invented a newand useful' Improvement in Rotary Brushes, of .Which the followingis a' specification, the principle of the invention being herein explained and the'best modein which I have contemplated applying that principle, so as to distinguish it from other-inventions.

The present invention, relating, as indicated, to rotary brushes, is directedlmore The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of variou mechanical forms in which the principle of the invention may be used.

In said annexed drawing Flgure 1 1s a side elevation of half of one ofmy improved brush sections; F 1g. 2 1s a second elevation showing the other side of the same section; Fig. 3 is an endor edge view of the section shown in Fig. 1, looking at the same from the right; Figs. 4, 5 and 6 are similar views. showing modifications .of the brush section; and Fig. 7 isa partial view in perspective of still another modification of my improvements.

My improved brush section-involves the use of a plurality of brush material retaining means, preferably employed in the form of retaining members such as inner and outer rings which may be conveniently formed of wire. The relation of thesemembers, here shown in the form of rings, is best shown'in Figs. 1, 2 and 3, in which the inner rings 1 are'shown as disposed concentrically within outer spaced rings 2 and 3. It is, of course, immaterialas to the precise number of the inner rings 1, and 'in the various views I have shown both one and two of these inner rings, while in Fig, 6 I have shown the ring in the form of an annular plate 4. The rings 2 and 3 are, as al- J I Specification of letters Patent. Patented Sept, Application filed J'ime 24, .1918. Serial No. 241,462.

ready stated concentric and radially outside oftheoinner rings. 1 and-lie in different planes, one ither' side'of the plane ofthe' The brush material consisting in theform illustrated of a plurality of bristles or rather wire strands 5, is'looped over the inner-or base rings 1 and 'is then brought within or between the two outer rings 2 and 3 so that the bases of. the loop are iii-close contact against the inner ring or ringsl, The outer rings are then secured together by sultable means which tie theloops 6 together and secoming loose and pullingthrough'between thetwo outer-rings and away from the inner ring. Such retaining-means conveniently ta'ke the form of the staples or wire wire 3 at intervals around the periphery .cure' the samev in place upon the inner rings I -1, preventing. any .of the bristles from 'beof the brush, and are so v eou -ed that they hold the two outer rings firmly together, locking the bristles in close engagement therebetween, and in this way snubbing the bristles about the inner rings 1 and preventing any looseness or spreading of the loops.

'My, improved brush may, of course, take various modified forms, such, for example, as is shown in Figs. 4 and 5, in which a double brush section is constructed by the use of two sets of the inner wires 1 placed side by 'side, and eachhaving brush material looped about'it, the material then. all clamped or tied between the outer rings 2 and 3. Still another modification is shown in Fig. 5, in which the inner rings 1 are crossed or interlocked as shown at 8, so that portions of each individual section lie in two parallel planes instead of in the same plane as in the brush section of Fig. 4.

In Fig. 6 I have shown a brush similar to the brushes of Figs. 1, 2 and 3, but with the inner ring in the form of a fiat. annular plate 4, which extends from the base of the loop in the brush material to a point but slightly within the. fastening staples 7. .In Fig. 7 I have shown a single inner ring 1 and a single outer ring 10, which lies in the same plane as the first-named ring, and to which the brush material is fastened by means of staples 9, each of which passes around a certain small bunch ofbristles, and fastens the same together and tightly against the ring 2. In this type of brush the ring 1 serves thesame purpose as in the previously de-V scribed forms, while the ring 2 serves as a means for retaining the bristle fastening means, namely, the staples 9 adjacent to the loops in the bristles, and prevents these staples from working radially outward. At

the same time this single ring 2 serves to maintain the bristles in the same plane in the same'manner as do the double outer rings shown in the other figures.

It is understood, of course, that these brush sections, such as I have described, are

intended to be assembled and used on a suitable mandrel, and may beused either singly or. in conjunction with a number of similar sections, and, of course, the presence of such v a mandrel within the hollow center of the "section also serves to prevent any of the bristles from working inwardaway from the inner rings 1.

' Other modes of applying the principle of I my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided themeans stated by any of the following claims or; the equivalent of such stated means be employe I therefore particularly point out and distinctly claim as my invention 1; A rotary brush section comprising a base ring, brush material looped .upon said ring, two other rings of larger diameter than and concentric with said basering and con- 2. A rotary brush section comprising a circular wire base, brush material looped upon said base, two other circulanwires of larger diameter than. and concentric with said base wire and contacting with said material on the respective sides thereofradially Iland staples passing through said material at spaced intervals and locking said-last beyond and wholly-clear of said base wire,

named wires together, whereby the 'loops'of' 7 place on said base ring.

3. A rotary brush section comprising a plurality of base rings lyingside by side,

brush material looped upon each} of said .materiahare tied together :and secured. inr rings, other vrings of larger diameter con- -i tacting with said material on the respective sides thereof radially beyond and wholly clear of said base 'rings,and means connect--- ing saidlast-named rings, whereby the loops 7 of material are tied together and secured 1 place on-said base rings.
